I'm sorry... You have 10GB of RAM and your first instinct is to get more?
What the hell is with this idiotic forum and it's obsession with 16/32GB of RAM? Have all of the Let's Plays rotted your brains or do you think "herpadurp skeedismincreft an cayptinspriklez has 32gb ov rem, dat meens i nede it two ur els i can no ran gam".
To answer your question, OP, no. CPU is "fine"(I'm using that word very loosely). The CPU uses Bulldozer cores, you know what that means...! Per core performance is abysmal. But hey, at least it outperforms the APUs in the next gen consoles.
You're fine on the memory front.
Considering the PS4's GPU is the equivalent to a desktop HD 5850, that HD 7450 doesn't even come close. It's such a basic card that it's enough to run most games at the very lowest of settings at <1080p. The card can't do 1080p gaming with a playable(24FPS or better) framerate.
All in all, if you did any research, you could have nabbed yourself something like a iBuyPower/CyberPower prebuilt with a A10 5800K if you had no intention of building your own.
